given the expression -x^2-6x+7,when expressed in form a(x+h)^2+k, the value of k is?
Answer: k = 16
Step-by-step explanation:
The equation is written in the form:
y = ax^2 + bx + c
y = -x^2 - 6x + 7
y = a(x - h)^2 + k where (h, k) is the vertex
a = -1 (from the original equation)
h = -b/2a (this is the equation for the line of symmetry or the x-value of the vertex)
h = -(-6)/2(-1) = 6/-2 = -3
when x = -3, y = ?
y = -(-3)^2 - 6(-3) + 7
y = -(9) + 18 + 7
y = -9 + 18 + 7
y = 16
(-3, 16) is the vertex
Since k is the y-value of the vertex, k = 16
I'll just take it a step further and write the whole equation:
Substitute all the values we found
-1(x +3)^2 + 16
-(x + 3)^2 + 16

Answer:
11Step-by-step explanation:
to understand thisyou need to know about:factor theoremtips and formulas:if f(c)=0 then x-c is a factor of f(x)let's solve:according to the question
2(-1)³+9(-1)+k=0
=>2(-1)+9(-1)+k=0
=>-2-9+k=0
=>-11+k
therefore
k=11

Ashley had a summer Lemonade Stand where she sold small cups of lemonade for $1.25 and large cups of lemonade for $2.50 if Ashley sold a total of 150 cups of lemonade for $265 how many cups of each type did she sell
Answer:
Step-by-step explanation:
S and L are the number of small cups and large cups, respectively.
S + L = 150
L = 150 - S
1.25S + 2.50L = 265
1.25S + 2.50(150-S) = 265
1.25S - 2.50S + 375 = 265
S = 88
L = 150-S = 62

Answer:
65 cm
Step-by-step explanation:
Hey There!
So the congruency statement ABC = TUV
states that side AB = side TU side BC = side UV and side CA = side VT
The given side lengths are BC and UV which are congruent to each other so we set up an equation to solve for x
7x+2=6x+11
step 1 subtract 2 from each side
2-2 cancels out
11-2=9
Now we have
7x=6x+9
step 2
subtract 6x from each side
7x-6x=x
6x-6x cancels out
now we have 9=x so x=9
Now we just plug in 9 to x in (6x+11)
to find the length of the given side length
6x9=54
54+11=65
Because side VU and side BC are congruent they both equal 65 cm
So we can conclude that the length of the given sides is 65 cm

the side of an equilateral triangle whose perimeter is 72 cm is ____
Answer:
24cm
Step-by-step explanation:
So a triangle has 3 sides and it is an equilateral triangle so each side should have the same length. The perimeter is 72 cm and that means we have to divide 72 by 3 and that equals 24cm.
Hoy hemos ido al cine 12 niños y 18 niños de mi escuela y 14 niños de otra escuela,si cada entrada cuesta $25 ¿cuánto se pagara en total?
Answer:
the amount paid in total is $1,100
Step-by-step explanation:
The computation of the amount paid in total is shown below:
= Total persons × cost of each one ticket
= (12 boys + 18 girls + 14 boys) × $25
= 44 persons × $25
= $1,100
Hence, the amount paid in total is $1,100
Gianna paid $4.75 for a strawberry smoothie. She now has $12.35. How much money did Gianna have before she bought the smoothie? Select all that apply.
m - 4.75 = 12.35
Add 4.75 to both sides of the equation.
Subtract 4.75 from both sides of the equation.
12.35 + 4.75 = 17.10.
12.35 - 4.75 = 7.60.
Gianna had $7.60 before she bought the smoothie.
PLEASE HELP
POINTS TO EARN IS 15
Answer: add 4.75 to both sides, 12.35+ 4.75 = 17.10
Step-by-step explanation:
For both of these, the total she had before the smoothie can be found by adding the cost of the smoothie back to the amount she has left.
Answer:
1. B. Gianna started with
2. D.subtraction
3. B. m – 4.75 = 12.35.

If a = 12 in and b = 25 in, what is the area of the pencil? A. 372 in2 B. 169 in2 C. 322 in2 D. 444 in2
Answer:
1169 in^2 Approx
Step-by-step explanation:
Given data
We know that the shape of the pencil is cylindrical
Hence the dimension is
Diameter= 12in
Radius= 12/2= 6in
Height= 25in
The surface area of a cylinder is given as
T.S.A.=2πrh+2πr^2
Substitute
T.S.A.=2*3.142*6*25+2*3.142*6^2
T.S.A.=942.6+226.224
T.S.A=1168.824
Hence the area is 1169 in^2 Approx
